what is another way to form (a+b)^c to another simple expression?
like for example a^c+b^c doesnt work because its not eqivalent to (a+b)^c
(without using squareroot)

im know of no way that is simpler. just look at the example of (a+b)^100.
how simple is that? or just try to simplify (a+b)^3.

I occasionally find it useful to write it as a^c * (1 + b/a)^c -- of course only when working over the reals.

it doesn't have to be simpler, just not so complicated. thanks CRGreathouse, that helps,
